Didda (c. 924-1003) was the ruling Queen of Kashmir for nearly 50 years (958-1003), first as regent then in her own right — founder of the Lohara dynasty. Called "the Catherine of Kashmir" by historians, she was politically ruthless yet a great patron of architecture and Buddhism. Kalhana's chronicle Rajatarangini (1148-49) gives her the longest treatment of any Kashmiri ruler.
Among the most consequential female rulers of medieval India.
Didda does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Didda reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
